Where holdings come from

Choice: Holdings come from the depository consolidated account statement (CAS) that CDSL or NSDL emails. The user sets one mail filter that forwards it to their private Chitragupt address. One statement covers every broker and the mutual funds under one PAN (features/0017-holdings-from-demat-statement.md). Every holding traces to an immutable source artefact. An Account Aggregator is considered only if a partner offers it free.

Why: the owner wants connect-once and free. Broker logins expire daily for Zerodha and Angel One, and an Account Aggregator charges per fetch.

Rejected: broker login or token connect for Kite, Upstox, Angel One and Dhan (shelved 2026-10-25) · the Upstox one-year token · storing broker tokens or TOTP secrets · a paid Account Aggregator · an onboarding broker nudge.
